Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497912, here are decompositions:

5 + 2147497907 = 2147497912
11 + 2147497901 = 2147497912
23 + 2147497889 = 2147497912
179 + 2147497733 = 2147497912
251 + 2147497661 = 2147497912
353 + 2147497559 = 2147497912
389 + 2147497523 = 2147497912
419 + 2147497493 = 2147497912

Showing the first eight; more decompositions exist.
